JOHN B. SMITH AND FRED HOBBISIEFKEN, OF GLENDALE, CALIFORNIA.

COMBINATION-T0913.

. Application filed January 2, 1917.

To all whom it may concern:

Be it known that we, J OHN B. SMITH and FRED HOBBISIEFKI-ZN, citizens of the United States, residing at Glendale, in the county of Los Angeles and State of California, have invented a new and useful Combination- Tool, of which the following is a specification.

This invention relates to combination tools, and more particularly to a hatchet attachment for claw hammers that will provide a combined hammer and hatchet.

The primary object of the invention is to provide a hatchet blade which is constructed so that it may be readily attached to an ordinary claw hammer without any chai'ige in the construction of the hammer and will provide a combined hammer and hatchet.

Another object of the invention is to provide an attachment of the above mentioned character which may be quickly and securely attached to a hammer and easily removed therefrom when desired.

A further object is to provide an attachment of the character described which is simple in construction, reliable in use, and inexpensive to manufacture.

In the drawings:

Figure l is a side elevation of the attachment as it will appear when in use.

Fig. 2 is a front elevation.

Fig. 3 is a fragmentary sectional v ew partly in elevation, particularly illustrating the means for securing the attachment to the hammer. V

Fig. 4 is a detail side elevation of the attachment removed.

Fig. 5 is a detail front elevation of the attachment removed.

Fig. 6 is l. horizontal sectional view taken on line (3-6, Fig. 3.

Fig. 7 is a side elevation partly in section of a modified form of the invention, and

Fig. 8 is a fragmentary detail front elevation of the modified form shown in Fig. 7.

Referring to the drawing, 1 designates a hammer head including a socket 2, claw 3, and handle 4 mounted in the socket 2.

My attachment comprises a hatchet blade 5, which, from a relatively thin sharpened lower edge 6 increases in thickness to its upper end, which is reduced and provided with a substantially V-shaped claw-receiving notch 7. The outer face 8 of the notch is relatively wide and flat and adapted to engage the outer face of the claw 3 of the ham- Specification of Letters Patent.

mer. This face is inclined downwardly and The opposite that is, is beveled on opposite sides, as at v claw and is wedge-shaped also.

The sides of the blade are recessed at 10 from the outer end of the notch so as to receive the wing portions of the claw 3. These recesses 10 taper downwardly to a point and are deeper at their upper ends so that the blade will engage snugly in the cleft of the claw. The upper end of the blade at the inner edge thereof engages in the cleft at the upper end thereof, as shown in Fig. 3 of the drawings.

The blade is held in position by a spring.- catch 11, which comprises a leaf spring 12 9, so that it will engage in the cleft; of the secured by screws 13 at its lower end to the outer edge ofthe blade near the upper end thereof. An inwardly pro ect1ng lug 13 is carried upon the spring 12 and is adapted to extend into a socket is which is embedded in the handle a at the end of said handle. The

upper end of the spring 12 is bent back upon itself to provide a gripping portion 1.5 to be grasped to remove the lug 13 from the socket 1 f. The eatch 11 serves to securely retain the blade in position.

To attach the blade to a claw hammer the claw is forced into the notch 7 so that it engages snugly therein, the opposed sides of the cleft portion of the claw resting in the ecesses 10. The face 9 of the notch engage in the cleft and upon the rear face of the claw, whereas the face 8 engages the outer face of the claw. When the. blade is thus positioned, the spring catch 11 will snap into position and the hammer maybe used as a hatchet.

In use itwill be seen that the greatest strain will be placed on the inclined wide face 8 of the notch, such face engaging the outer face of the claw. he face 9 and upper edge of the blade on the inner side thereof also receive some of the strain and through these faces the blade is securely held in position. The beveled sides of the face 9 engage the beveled faces of the cleft in the claw 3, as shown in Fig. 6.

It will be seen that to adapt an ordinary claw hammer for use in connection with the attachment, it is only necessary to embed the socket 1% in the outer end of the handle 4;.

Referring to Figs. 7 and 8 wherein I have illustrated a modified form of the invention, 16 designates a hammer head having a socket 17, claw l8 and a handle 19 pivoted in the socket 17.

There is provided a blade 20 which is similar to the blade 5 in the preferred form of the invention in that it is provided with a claw receiving notch 21, and the outer face of the notch 21 is flat whereas the inner face of the notch is beveled on opposite sides as at 22 so as to engage in the cleft of the claw as does the corresponding face in the preferred form of the blade. This form differs from the preferred form in the catch for securing the blade to the hammer.

In the outer face of the notch 21 there is formed a longitudinal recess 22 in which is mounted a leaf spring 23, the spring being welded or otherwise secured in the notch. The notch at the upper end is deeper than at its inner end so as to permit a certain amount of movement of the spring 23. A projection or lug 2% is carried on the spring 22 and is adapted to extend into an opening 25 therefor formed in the head 16 of the handle. The outer end of the spring is turned back upon itself as at 26 to provide a portion to be grasped when removing the lug 2% from the opening. This form is used as the preferred form and can be attached or removed as readily.

N e claim:

1. A hatchet attachment for claw hammers comprising a hatchet blade having a claw receiving notch in its upper end and claw-receiving recesses extending along opposite sides of the blade from the inner end of the notch therein, and means carried by the blade adapted for cooperation with a hammer to hold the blade thereon.

2. A hatchet blade attachment for claw hammers comprising a tool blade having a claw-receiving notch in its upper end, one face of said notch being relatively wide and flat to engage the outer face of the claw, the other face of the notch being beveled and wedge-shaped to engage in the cleft on the inside of the claw.

3. A hatchet blade attachment for claw hammers comprising a hatchet blade having a claw receiving notch in its upper end, one face of said notch being relatively wide and flat to engage the outer face of the claw of a hammer, the other face of the notch being beveled and wedge-shaped to engage in the cleft on the opposite side of the claw, said blade being provided on opposite sides with downwardly tapered recesses to receive portions of the claw at the opposed faces of the cleft thereof, and a leaf spring secured to the blade, said hammer having an opening therein, and. a projection carried by said spring and engaging in said opening to hold the blade upon the hammer.

i. A hatchet blade. attachment for claw hammers comprising a tool blade having a claw receiving notch in its upper end, one face of said notch being fiat to engage the outer face of the claw, the other face of said notch being beveled and wedge-shaped to engage in the cleft on the opposite side of the claw, a longitudinal recess in the first named face of the notch, a leaf spring mounted within the recess and extending beyond the upper end of the blade, and a projection on the spring adapted to engage with the hammer.

5. A hatchet blade attachment for claw hammers comprising a tool blade adapted to be removably attached to a claw hammer having a claw-receiving notch in its upper end and being provided on opposite sides with longitudinal recesses to receive the opposite sides of the cleft of the claw therein, said recesses extending from the inner end of the notch, the upper end of the blade being adapted to engage the hammer at the inner end of the cleft portion of the claw, said recesses being substantially V-shaped in cross section to conform to the shape of the claw on opposite sides of the cleft therein, and means to removably secure the blade to av hammer.

Signed at Culver City, Cal, this 19th day of December, 1916.
